I have been trying my best to strip the wiring harness
down. This is what I've done so far: I went through a Legacy ECU pinout,
and labeled/sepparated every wire that pertained to the ECU. Was this
the correct way to go about it? Now I have a large pile of wires that
didn't directly go to the ECU, and then the four plugs and their
corresponding wires that connect to the ECU. Are these all I will need?
Or did I just make myself a mess...? Also, what is the "Select Monitor Signal"? Necessary?
